Good Afternoon!

In this engaging lesson, students will dive into the world of polymers by exploring Polyvinyl Alcohol (PVA). The activity involves building models of PVA molecules using specific materials, allowing students to visualize and understand the relationship between monomers and polymers. Safety precautions will be emphasized, and students are encouraged to collaborate in pairs to share materials. Additional analysis and extension questions on different plastics will enhance their learning experience and promote inquiry-based science.
